Tom Suozzi’s campaign manager abruptly resigned yesterday in yet another sign of trouble for his long-shot bid to defeat Eliot Spitzer in the Democratic primary for governor.

The resignation of Kim Devlin came the same day The Post quoted a top state Democrat, Hillary Clinton advisor Howard Wolfson, as warning Nassau County Executive Suozzi that he was in danger of “ending his political career” because of several tough personal attacks he directed at Attorney General Spitzer – after pledging never to do so.

Devlin’s resignation also came days after a Suozzi campaign filing revealed he’d raised only $2.8 million since January – compared to more than $10 million raised by Spitzer.

Several recent public opinion polls have shown Suozzi trailing Spitzer in the Sept. 12 primary by a seemingly insurmountable 50-plus percentage points.

Devlin, a longtime Suozzi loyalist credited with helping the onetime Glen Cove mayor become his county’s first Democratic executive in decades, will remain on with the campaign as an adviser, Suozzi said in a statement.

“We don’t know what went wrong with the campaign but we do know that we have absolutely no traction with the voters,” said a source close to Suozzi.
